This was really a nice change of pace from typical mac and cheese. I made this exactly as posted, cooking it for 25 minutes. I really didn't notice the lime juice but I did enjoy the kick from the sausage and pepper jack cheese. I'd say it serves 3 generously. Made for ZWT 8.
Delicious, rich and very spicy (even with half the cheese and 8 ounces of dry pasta!). The recipe comes together quicker than it looks too. For us this fed 2-3 (with that amount of pasta).
The pepper jack, chorizo, and fresh lime juice make this homemade mac and cheese extra zippy!
